Job description

What You’ll Do

The Senior Staff Software Engineer is one of Nue's senior-most individual contributors, responsible for shaping the technical direction of the platform across multiple product teams. This role sets the multi-year technical strategy in their domain, drives the architecture decisions that other teams build on, and operates as a force multiplier for engineering — through code, design, mentorship, and judgment. They lead through technical excellence, deep system understanding, and a track record of consistently making the right call.

Set multi-year technical direction

• Define the technical roadmap for a major platform area (e.g., lifecycle management, billing, integrations, data platform) across multiple teams and quarters.


• Make build-vs-buy and platform-vs-feature trade-offs at the company level, with clear written rationale.


• Sequence the technical investments that unblock the company's largest customers and the next two years of growth.


• Bring a strong, well-reasoned point of view to architecture reviews — and the credibility to push back on leadership when the data warrants it.

Architect systems other teams build on

• Design and lead the implementation of foundational systems — distributed services, data flows, APIs, integrations, and shared libraries — that span product teams.


• Lead non-trivial migrations and modernizations: HA upgrades, language/framework moves, monolith decompositions, schema changes, multi-region rollouts.


• Set the technical standards for service ownership, API contracts, observability, and reliability that every team adopts.


• Own the architecture of one or more business-critical flows end-to-end (e.g., quote-to-cash, billing, sync).

Ship code that matters

• Stay deeply hands‑on. Lead the implementation of the highest‑leverage and highest‑risk projects yourself.


• Write code that becomes the reference example for what \"good\" looks like at Nue.


• Pair with senior and staff engineers on the hardest problems; unblock teams stuck on technical depth.

Drive customer outcomes through engineering

• Be the technical owner for the engineering work that unblocks Nue’s largest customers.


• Convert ambiguous customer asks into bounded engineering work with clear scope, owners, and dates.


• Be on the call when production is on fire for a strategic customer — and be the senior‑most engineer making the call to roll forward, roll back, or escape.

Coach and mentor other engineers

• Mentor and develop staff and senior engineers across the company. Help two or three of them grow into staff or senior staff over the course of the year.


• Embed deep technical thinking into design reviews, code reviews, and engineering planning across product teams — not just your own.


• Build internal tools, shared libraries, and AI‑assisted workflows that let every engineer ship faster.


• Champion engineering excellence: testing, observability, security, performance, and operational maturity.

Drive engineering excellence at the org level

• Help define the engineering standards the org operates against — testing strategy, observability bar, security posture, dev productivity, code review norms.


• Partner with engineering managers, the CTO, and product leadership to translate strategy into engineering execution.


• Champion AI‑assisted engineering as a first‑class capability — prompt libraries, agents, and internal tooling that compound the team’s leverage.


• Raise the bar in hiring: act as a bar‑raiser, calibrate levels, and grow the senior IC pipeline.

Be the company's senior technical voice

• Represent Nue’s engineering org in critical customer conversations, vendor evaluations, and partner integrations where deep technical credibility is required.


• Contribute to public engineering presence where it serves the company — talks, posts, OSS — without losing focus on internal impact.

What You’ll Bring

• 12+ years of professional software engineering experience, with a sustained track record of operating at staff level or higher in a high‑bar engineering org.


• Demonstrated track record of designing and shipping foundational systems used by multiple teams — services, frameworks, data infrastructure, or shared platforms.


• Deep expertise in at least one modern backend stack (Java/Spring, Node/TypeScript, Python, Go, or similar) with strong fluency in at least one more, plus the design judgment to know when each fits.


• Strong systems‑design ability: distributed systems, data modeling, consistency trade‑offs, performance, scaling, and reliability — proven on systems with significant production load.


• Hands‑on production expertise across cloud infrastructure (AWS, GCP, Azure), Kubernetes, CI/CD, and observability tooling (OpenTelemetry, Prometheus/Grafana, or equivalent).


• Strong fluency with AI coding tools (Claude Code, Copilot, or similar) and a track record of materially accelerating both your own work and your team’s through them.


• Demonstrated track record of leading a team or org through a significant architectural transition (HA migration, language/framework move, multi‑region, monolith → services).


• Track record of mentoring senior and staff engineers; multiple engineers will say you were materially responsible for their growth.


• Excellent written and verbal communication; comfort defending technical positions in front of executive leadership.
